Hi Subha,
Currently, we do not have support for Editor control to create, edit, and format RTF documents in Xamarin platform. Please use the Xamarin DocIO library (non-UI component) to create, edit and save the Word, RTF documents in C# code based on the DocIO object model.
For more information about DocIO library, please refer to the below help documentation link.
Could you please let us whether the Editor control term in query refers to any of our control ? If so, please provide us screenshot or other information about editor control. This will help us to provide the appropriate solution at the earliest.
Regards,
Ramya T
